Abstract: ABSTRACT OF THE DISCLOSURE          There is disclosed herein a nuclear magnetic resonance apparatus for testing body fluids for a constituent, for example, blood for glucose.  The apparatus includes a principal magnet, a magnetizable coil, and a circuit for energizing the coil for energizing and realigning molecules and detecting changes resulting from relaxation of said field and analyzing said changes.  The apparatus is compact and adapted to receive and test an extremity or vessel carrying a body fluid.  The coil is constructed to be positioned adjacent the extremity or vessel to be tested.  Circuit means are provided for energizing the coil to energize and realign molecules adjacent said coil, so as to permit molecules adjacent said coil to assume an aligned position and for sensing changes in position when the coil is deenergized, which is indicated by spectra having peaks corresponding to various molecular bonds.  The circuit also includes means for comparing the actual value of a peak for a first constituent to A predetermined value for the peak of said first constituent and determining the actual value of a second constituent from a predetermined relationship between the values of the peaks for the first and second constituents. Specifically, predetermined water and glucose peaks are compared with the measured water and glucose peaks for determining the measured glucose concentration.

Abstract: ABSTRACT OF THE INVENTION      PREPARATION OF PHENOL HAVING IMPROVED CLARITY            WHEN DISPERSED IN WATER This invention is a process for preparing phenol having improved clarity when dispersed in water.  The phenol is prepared from crude phenol being the product of decomposition of cumene hydroperoxide and having previously been distilled to remove large portions of acetone, cumene and alphamethyl styrene.  The method of the invention comprises a)  introducing the crude phenol as a feed to a fractional distillation column, the column having many theoretical distillation stages and having a condenser for overhead vapors, b)  heating the bottoms of the fractional distillation column to vaporize the phenol and lower boiling components of the crude phenol, c) removing those components of the crude phenol boiling higher than phenol from the bottom of the distillation column, d)  removing substantially dry liquid phenol product from the distillation column at a point at least one theoretical stage from the top of the column, the phenol product having improved clarity when dispersed in water, e)  adding water to the top of the fractional distillation column in an amount sufficient to improve the clarity of the phenol product when dispersed in water, but not in an amount great enough to cause the phenol product to contain more than 0.1 percent water by weight, ABSTRACT OF THE INVENTION (Continued) PREPARATION OF PHENOL HAVING IMPROVED CLARITY          WHEN DISPERSED IN WATER   f)  removing a condensed liquid phenol-water mixture containing impurities overhead from the top of the fractional distillation column, and g)  returning a portion of the phenol-water mixture to the top of the fractional distillation column as reflux.

Title: Electro-optic switching devices using ferroelectric liquid crystals
Inventor: HANDSCHY MARK A
IPC: G02F1/315

Granted: 1992-04-28
Abstract: ELECTRO-OPTIC SWITCHING DEVICES             USING FERROELECTRIC LIQUID CRYSTALS                  ABSTRACT OF THE DISCLOSURE     An electro-optic switching device using ferroelectric liquid crystals to either transmit or reflect the incident light depending upon the molecular orientation of the ferroelectric liquid crystal molecules.  An applied voltage causes the ferroelectric molecules to switch from a first state in which the incident light is substantially transmitted to a state in which the incident light is substantially reflected.  This is accomplished by effectively changing the refractive index of the ferroelectric liquid crystal in the different states.  The ferroelectric liquid crystal is disposed between two dielectric mediums such as glass so as to define a boundary which either causes incident light to change direction or its complex amplitude to change, and the smectic layers of the ferroelectric liquid crystals are oriented such that the incident light is selectively switched to one or more outputs.  The molecules are also oriented so as to rotate in a plane perpendicular to the applied field, thereby reducing the switching time between the first and second molecular orientations.  In addition, the switching effect may be made operative solely by the presence or absence of light by generating the applied electric field from the incident light.

Abstract: ABSTRACT OF THE INVENTION     In a data processing system, there is included a central processing unit  (CPU)  and a main memory for storing  computer words,  the  CPU  including  a  cache unit.   In operation, the CPU requests that a computer word be fetched, the computer word to be fetched being identified by a real address location corresponding to a location where the predetermined computer word is stored in main memory.   The CPU request to fetch the computer word is coupled through the cache unit such that the cache unit determines whether  the computer word is stored within the cache unit.   The cache unit comprises a cache for  storing predetermined ones of the  computer words. A  directory  is  included  for storing  partial  real  address  information  to  a corresponding computer word stored in the cache.   A detecting element, operatively connected to the cache and to the directory,  determines when a hit  occurs without  any  errors.    Control  logic,  operatively connected to the detecting element, makes available to the CPU the requested computer word from the cache or the main memory when an error is detected as a result of  attempting to obtain the computer word from the cache.

The scale inhibitor solution employed in this method avoids premature plugging of the formation, substantially extends the life of the treatment and the polyvalent cation complex of the polyacrylate is fully inhibitive.
